Figure 2 is a plan view of tlie upper portion of tl1e same, with 1;he block-carriage removed.

Flgure 3 ropresents the rotai*y block-omriage, ztnd Figure 4 is a. sectiona.l view, showing the constructlon of aspring-stirrnp used in adjusting the blooks.

Power is communicated to the main pulley, N, and from lt,- by meanS of appropriate belts and pulleys, to the ciroular saws A B antl plzmexs O D; also, by means 0f a. friction-pully, M, o r suitable cog-gearing, to the rot-ary block-carriage G. 4

Blocks, of suitable lengt-h, from whiol1 shingles'are to be made, are plaoed in the openings S S, 8m, in

tl1e block-carriageG, und secured by mezms of tl1e The "dogs am provided with plns b b, &c. that impingo upon the inclined arm sE E, by whicl1 tbey are slightly raised, and the blouks released.

Below the block-carriage' are situated adjustable stirrups W X Y, und an a ljustable Spfing-stirlup, Z. \Vhen the'shingle-blooks a re released by the dogs L L, &c. as above described, they fall upon a. pn-ir of tlxese stirrups,atnd am adj ustedroacly f0r. the next planerand saw.

Tlxe stirrup Z is provid ed with spiral springs, as shown in fig. 4, tha .t allow it t o be depressed by the seveml inelinecl planes 1 I, &c., situated 0|r1 the under side of the block-oarriuge.

'll1e objectzof this mmngement is to provide for tl1e unclist-urbed pa-ssage of tlxe butt of tl1e sl1ingle over tl1e -stirxup that zuljustecl tl1e block for the point; as, for

exmnple, wl1en zu block has passed tlxe saw B, its under surfa.ce will be in zu horizontal plane. 'll1e next shingle is to be sawn from the point, and in order to properly acljust the block. tl1e 1ear stirrup, Y, must be as muol1 l0wer than the forward one, Z, as tho (lifference in thickness of the two ends of tlve shingle.

'll1is difierenoe in the height of tl1e stinups must now be Overcome, tliat the 1ezu eml of tl1e block, mljusted for tl1e butt of tl1e shingle, nmy pass undisturbed, to aocomplilsh whioh is tl1e objeet of tl1e devi ees above describecl.

Tl1e adjustable stirrups, W X, lmve likewise a. difference in lleight equul to tl1e cliflelence in tl1ickness' of tl1e two emls of tl1e shingle, bot in this case, as tl1e butL of the shingle is 1:0 be sawn from alle forward end of tl1e block, no furtber adjustment of tl1e stirrup s is r equired. 1

'lhe planers 0 zyncl D a1e so place'd tlmt tl1e block reaches tl1em after it l1as been zuljusted for tlxe next shingle, und in consequence, its lower surface is inclin d to tl1e horizontal surface of tlie planer, whiolx latter may be set to meet tl1e block 'atany glven p oint in tl1e incliue.

. Sl1ingles mzule in tl'1is mzuiner will be of eveh tl1iokness where planed, t he 'inclined part being lel'li rougl1 as il; comes from t-he szuv. v
